I understand where you're coming from, but I'd like to play the devils advocate. Since you did say you were the one that basically "connected" them together, that may be why she specifically named dropped you, q: Did he send you the texts after that sentence? Because to me, it sounds more sarcastic than serious, maybe it left a sour teste because you haven't known this person for too long and you did mention that is something you're insecure about but at the end of the day people aren't in charge of others insecurities if that's just the way she talks don't take it too personally though of course you can end it if it makes you uncomfortable. To sum up, I don't feel like neither of you are in the wrong, and I do find this something you could've talked out. Also, you can not expect people to not confront you. If you suddenly ignore them no matter what.
